WordPress Performance Trac tickets

• @westonruter shared work on #61734 / PR #8815 adding fetchpriority support for Scripts and Script Modules.
• @spacedmonkey shared a desire to see some eyes on #59592
  • @spacedmonkey says it seems to have a massive effect for those using object caching. The change has unit tests and has been been reviewed by a non committer. Just needs another committers to give it the thumbs up.
  • @spacedmonkey would like to land this ASAP, to allow as much time as possible to test this change.
  • @rmccue confirmed support for the proposal but cannot review the code in the short term.
  • @westonruter asked whether there’s TTFB benchmarking data available for the patch.
    • @spacedmonkey noted there would’t be any noticeable difference there. This change would help high traffic site and helps database and object cache performance.
    • @tillkruess noted It will just reduce memory usage in the cache significantly, or make it easier to keep it low.
• @spacedmonkey noted that #58001, #63021, and #57496 are still awaiting a second round of review.
  • @mukesh27 mentioned @flixos90 already reviewed and shared some feedbacks for #58001 / PR #5098.
  • @swissspidy added that the other PRs have some merge conflicts that could use a refresh.

Open Floor

• @b1ink0 brought up some confusion around the bug scrub timing, asking if the schedule should be revisited to avoid conflicts. (Bug scrub schedule link)
  • @westonruter asked if the time had already been moved to avoid conflicting with core dev chat.
  • @westonruter confirmed that, according to the Make Meetings page, it had not been adjusted.
  • @swissspidy suggested moving the bug scrub to Tuesdays on alternate weeks from office hours.
  • @westonruter and @flixos90 both supported the idea.
  • @swissspidy updated the Make Meetings page and Bug scrub schedule, then shared the schedule for the next meetings as follows:
    • May 27 – bug scrub (potentially led by @adamsilverstein)
    • June 3 – office hours (@swissspidy would probably cancel that one because of WordCamp Europe)
    • June 10 – bug scrub
    • June 17 – office hours
